All eyes on China Despite China’s slow GDP growth this first quarter, US-based players in the chemicals industry remain fearless of the shrinking demand as they continue to leverage new and existing solutions to further expand their market footprint. Two words were prominent during this year’s Chinaplas exhibition: investments and product developments, with higher demand of goods anticipated over the medium to longterm owing to strong consumer spending and urbanisation in China, says Lyn Cacha in this report.
In nonwovens, ExxonMobil’s Vistamaxx elastomers are inspiring breakthroughs

he general sentiment in the material suppliers and processing community is to do more with less, especially with downgauging, wherein the amount of material in a packaging is reduced while still maintaining or even improving the properties. Improved plastics offer tremendous downgauging opportunities, emphasised Haridass Kalidas, PE AP Market Development Manager of ExxonMobil Chemical. According to Kalidas, consumers are demanding more sustainable film products made from fewer resources. And at the same time, they are not inclined to accept any loss in performance of the packaging material, forcing processors to come up with material solutions to solve these requirements. To showcase its Exceed and Enable metallocene polyethylene (mPE) resins, the company was running the resins on machines in various halls. A three-layer 70 micron collation shrink packaging film using Enable mPE resin was shown at Sun Centre’s booth; a three-layer 125-micron film for heavy duty sacks using Exceed and Enable mPE resins was shown at HanKing’s booth; three-layer 50-micron packaging film using an Enable mPE/C4 LLDPE resin blend was processed at Hubei Light Industry’s booth and three-layer solution using Vistamaxx-based filler masterbatch for HDPE film for shopping and garbage bags at HuaShan’s booth. “The resins have improved processability for our customers, in terms of optics and colour. More importantly, processors are able to downgauge – to make films thinner using less materials and using less energy to make the same products with much better properties,” added Kalidas. For nonwovens, the firm’s Vistamaxx propylene-based elastomers are inspiring breakthroughs while enhancing performance at reduced costs. “Aside from the ability to downgauge, the other unique attribute that Vistamaxx brings is softness. You feel the film, it is PP-based but it has the softness and elasticity that is important in films. For instance, when making diapers, you want it to be soft with no noise,” said Anthony Soo, Vistamaxx Films Global Business Development Manager. In terms of expansions, ExxonMobil is bolstering its petrochemical operations in Asia, doubling its integrated petrochemical complex in Singapore by a capacity of 3.6 million tonnes and streamlining processes at its Chinese facility in Fujian. In Singapore, it is adding on 1 million tonnes of ethylene; 1.3 million tonnes of PE; 500,000 tonnes of PP; 300,000 tonnes of speciality elastomers; 340,000 tonnes of benzene and 125,000 tonnes of oxo-alcohol. In Fujian, it is debottlenecking the steam cracker and its derivative units. It is also planning to enhance processing of light feedstocks to help strengthen its integrated PE position and expand capability to meet global demand growth. Meanwhile, its fully operational Shanghai Technology Centre (STC) occupies 27,000 sq m and is equipped with more than 200 types of equipment as well as commercial and pilot scale lines. Resin design and testing emphasised With the many available solutions that enable downgauging, Dow Chemicals says that resin design and consumer testing are essential to help the processor determine which materials will work best for different applications. According to Dow, it has done a study and discovered that customers do notice the changes, such as feel and thickness, and that material processors are placed in a difficult spot wherein they need to anticipate brand owner, retailer and consumer expectations. When downgauging, Dow recommends that processors should consider choosing the right resin design; utilising a high bending modulus and doing minor (i.e., 5%) gauge reduction. In the end, the processor must ensure that the consumer packaging company and consumers cannot tell the difference made to render a more sustainable package.
